Interesting heat pump information

Really interesting. I was paging through the heat pump’s main menu on the unit itself and found a section called ‘Information’. When I looked into it more I found it had the following sub-menu.

‘Malfunction history’ was interesting because it showed there was a repetitive problem labelled ‘Water flow problem’ on the morning of installation which probably explained why the engineer was on his phone so much. However, as all now seems to be working what I was more interested in was ‘Energy data’ and when I selected that the following sub-menu came up.

That caught my attention so I decided to immediately investigate ‘Energy input’ and was treated to the following data screens showing the heat pump’s consumption of energy by day, week, year to date and since commissioning. I was really impressed.

Then I decided to look at the data for ‘Produced heat’, was presented with a similar set of data screens and was even more impressed!

Amazing! So with an input of only 14 kWh since the pump was installed on Thursday it has produced a heat output of 72kWh, over 5 times as much! That figure blew me away. I’ve previously read about heat pumps having a performance factor of 3x but to be getting over 5x I find to be almost unbelievable.

I don’t know what this means for the future – it’s still very early days and the outside temperature is still relatively warm at 16 degrees C. However, the heat pump specification sheet says that even with an outdoor temperature of -15 degrees C the pump can produce an output temperature of 65 degrees C. I find that amazing and very encouraging as I think that that should be quite adequate to keep my new house very cosy through the winter months here in the Dordogne 🙂
